Open Nuclear Network (ONN)

Open Nuclear Network, ONN (Austria)

Open Nuclear Network (ONN) is an independent non-advocacy NGO established in Vienna, Austria. Its mission is to reduce the risk of the use of nuclear weapons in response to human or technical error, uncertainty or misdirection, particularly in the context of escalating conflict. ONN’s diverse team of analysts produces operational insights, using non-classified sources, leveraging publicly available data and technology through our specially developed software platform ( and deploying a network of trusted third parties, known as the Engagement Network, to improve dialogue and promote nuclear de-escalation.

The first year of our operation, we will be focusing on the Korean Peninsula. We hope to contribute positively to the shared goal of de-escalation.
